Design Experiment: Enzyme Inhibitors. Research question: What is the effect of adding lead nitrate solution on the activity of amylase enzyme? Aim: To test the effect of adding nitrate solution on the activity of amylase. Background Information: Inhibitors are molecules which repress or prevent another molecule from engaging in a reaction. They are substances that attach themselves onto an enzyme and reduce or prevent the enzyme’s ability to catalyse reactions. Competitive Inhibitors are inhibitors

Bugs Attraction to Colored Lights Introduction: This experiment was conducted to see which colored light pill bugs would prefer more out of red‚ blue‚ yellow‚ and green lights. If pill bugs went to the green and yellow lights more than the blue and red lights‚ then this means they like brighter lights more than gloomier lights. For the experimental group‚ the colors used were blue‚ red‚ yellow‚ and green. The controlled group was the middle chamber. It got regular light from the classroom. The independent

22 May 2013 Light Pollution Sin City‚ better known as Las Vegas‚ full of its twinkling bright lights and flashing advertisements at night‚ is a huge tourist attraction. However‚ can you look up at the desert sky and see the Milky Way? The answer to this question is no. The light pollution in Vegas is so strong that it can be seen from outer space. Light Pollution is misdirected and misused light. This results from an inappropriate application of exterior lighting products. Light Pollution comes

Experiment : 1 Tittle : Preparation of bis(acetylacetonato)copper(II) complex Objective : To synthesis the bis(acetylacetonato)copper(II) complex Introduction : A complex ion is usually form with high charge density metal ion as a central and formation of coordinate covalent bond (dative bond) with high electron molecules or ions. These molecules or ions are functioning as ligands (electrophile in organic compounds). They are easily attracted by electrophile (electron deficiency

Photosynthesis and cellular respiration go hand in hand‚ but there are differences of the two that most people overlook. Without either of these processes though‚ the human species wouldn’t exist. Along with every other plant or animal. Photosynthesis starts off the cycle‚ with light energy being trapped within the cell and transported into the chloroplast. Water and carbon dioxide follow the similar route of the light energy and as so is collected into the chloroplast. Photosynthesis tends to take

PHOTOSYNTHESIS (How do the light dependent and light independent reactions provide food for a plant?) Why? How important are plants to life on Earth? Could life as we know it continue if there were no plants? Read on the find out why plants are truly the cornerstone of life.

Photosynthesis and Respiration Unit2 – IP 1. A) Photosynthesis space is a process in which the energy from light is used to produce carbohydrates. Aside from using light energy‚ photosynthesis includes carbon the oxide and water. A1) In order to generate energy aerobic respiration requires oxygen‚ although fats and proteins and carbohydrates can be consumed and processed as reactant‚ is the usual method of breaking down in glycolysis and usually requires the pyruvate to enter the mitochondrion

Abstract The process of photosynthesis can be summarized as the photoautotroph consumption of carbon compounds as food and release of oxygen compounds as waste. The methods to measure the rate of photosynthesis are various. One method utilizes CO2 sensors to measure photoautotrophs CO2 intake under various luminescent environments. An elementary method utilizes H2O and NaHCO3 (Sodium Bicarbonate) for submersion of deoxygenized photoautotroph specimens to measure the release rate of oxygen compounds

Speed of Light Determining the speed of light is something that has been a very long and trying process. No one scientist could determine such a thing. Galileo was the first noted scientist to attempt experimentation on the speed of light. Other famous scientist‚ such as‚ Roemer‚ Foucault‚ Fizeau‚ Michelson‚ and Einstein added their own discoveries to the collage of information gathered through the years. Every scientist performed their experiments differently based on the knowledge and ability

What is light produced‚ reflected and refracted into visible light? Refraction is the bending of a wave when it enters a medium where its speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media. The definition of produced visible light means when the electromagnets radiation meets the human eye. The first example of produced is a glow stick because it produces its own light . Another
